CASH-REGISTER.

SPECIFICATION forming part of Letterslatent No. 480,614, dated August 9, 1892. Application filed October 30, 1891 Serial No. 410,333. (No model.)

To all whom it may concern.-

Be it known that I, HENRY G. ONEILL, a subject of the Queen of Great Britain, and a resident of Louisville, in the county of J offerson and State of Kentucky, have invented certain new and useful Improvements in Cash- Registers; and Ido declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in [O the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

I 5 Figure l of the drawings is a vertical transverse section. Fig. 2 is a front elevation, partly in section. Fig. 3 is a top plan view. Fig. at is a detail view of adding-wheels and their attachments. Fig. 5 is a detail view.

This invention has relation to cash-registers; and its object is to provide an attachment for some machines of common form using a series of key-levers whereby the aggregate value of the transactions indicated by the ma- 2 5 chine will be made known upon inspection of a series of adding-wheels, all as hereinafter set forth.

In producing the devices and combinations which form the subject-matter of this application I have designed not to interfere materially with the construction and arrangement of parts adopted in many cash-registers, in order that the improvements may be readily connected to such machines at a minimum 3 5 expense.

In the accompanying drawings, the letters A and A designate two shafts, each being about one-half the length of the machine and each carrying near its end a toothed wheel, as

indicated at E and E. These shafts may be supported in bearings of the lateral frames 0 and O and of a middle upright or frame D.

Z and Z indicate bail-levers, which have arms a and a and b and b, respectively, said arms being pivoted on said shafts or in the axial line thereof near their ends. Each of these bail-levers is provided with a pawl and with a series of projections or arms G, extending downward, respectively, over the various 5o key-levers, which extend under said bail-bars, said projections or arms being graduated in length to correspond, respectively, with the working movements of thekey-levers. These bail-levers extend transversely over the keylevers, one bail-bar traversing the lovers of the cent series and the other bail-bartraversing the levers of the dollar series, and each baillever being common to all the keys of its series.

The downward projections or arms G are of different lengths, because while the actual movement of all the key-levers of the machine is similar, its working movementthat is to say, that partof its movement in which it is actually in engagement by its pawl with the toothed wheel E or E of the adding mechanism-varies, according to the radial distance through which such wheel must be moved to transmit the value of the key to the addingwheels. The working movement of the fivecent key will be much less than that of the twenty-five-cent key, and therefore the downward projection or arm of the bail-lever corresponding to the five-cent key will be materially shorter than that which corresponds to the twenty-five-cent key.

For registers of limited capacity having a small number of keys the sectional division requiring two bail-levers will be unnecessary, as a single bail-lever will meet the requirement; but for large machines, when the keys are numerous, the sectional division involving two bail-levers, each having its own pawl and operating an independent toothed wheel for transferring its value, will be found more practical. In this sectional arrangement-the bail-lever Z on the right is actuated by the key-levers of the cent series and the bail-lever Z on theleft is actuated by the key-levers of the dollar series; but while the bail-lever 0 of the cent series is always in connection through its pawl, toothed wheel, and pinions with the adding-wheels, that of the dollar series is normallydisconnected from the addingwheels and its pinion is brought into engage- 5 ment with the first of the dollar-adding wheels by the action of any key of its series, as hereinafter described.

E and E are the large toothed wheels which are engaged by the pawls of the bail-levers, zoo respectively. These wheels are located conveniently at points on the inner sides of the lateral frames 0 and C, respectively, in such position as to be turned by one of the pawls .9 upon movement of the graduated bail-lever Z or Z, as the case may be. Pawls e are designed to hold the wheels E and E 1n place while the graduated bail-bar 1s resuming its normal position, having passes through an arc corresponding to the value of the key struck. Springs may be employed to retract the bailbars.

The letter Grepresents the downwardly-extending shoulders, arms, or projections of the bail-bars, which, as hereinbefore stated, are of graduated lengths, in order to effect the correct movement of the toothed wheels E and E to make the addition.

In order to avoid the sliding of the end of the arm G on the key-lever as it rises and the consequent friction, it is preferred in large machines, or where the bail-bar 1s des gned to move through a considerable arc, to pivot the arms G to the bail-bar and to provide stopshoulders g and springs g to hold these arms in normal position when the keys are down and disengaged therefrom. At an elevation above said wheels E and E and between the side frames'O and C and mediate supports are the transverse pinion-shafts K and K, on which, so arranged as to be in engagement with the wheels E and E, respectively, are the pinions 7a and 7c, and upon suitable bear ings is arranged a series of adding-wheels side by side and turning in planes at right angles to the direction of the pinlon-shafts. These pinion-shafts are of the construction shown, wherein the adding-wheels are centrally arranged, provided with secondary pinions is and to engage, respectively, the first of the cent-wheels of the adding series and the first of the dollar-wheels of the same; but it will be observed that whereas the first cent-wheel is always in engagement with its pinion the dollar-wheel-actuating pinion is normally disengaged from the first dollarwheel, being held back by a spring N, connected to the pinion-shaft K, which is carried by the arms Z of the bail-frame L, which is pivoted at Z and is moved when any one of the dollar-keys is operated by the lug lot the dollar-key, this movement bringing its pinion 70 into engagement with the first wheel of the dollar series.

The adding-wheels are arranged in series on a suitable shaft 177. and turn in planes transversely to the direction of said shaft. The first two wheels H and H on the right serve to show the number of cents in the sum, the remaining wheels I I I on the left showing the dollars. The first wheel H of the cent series is constantly in engagement with the pinion it; but the first wheel I of the dollar series is normally out of engagement with the pinion 76', as hereinbefore stated.

The series of adding-wheels is provided with carrying-pinions J and with peripheral stoppins 19. A slide-frame M, arranged on the shaft on and slotted at m, may be moved back and forth a distance limited by said slot and is designed to be secured in its rear or forward position by means of clamp-screws f. This slide-frame carries on its rear bar the carrying-pinions J, and its front bar J constitutes a stop to engage the peripheral stop-pins of the adding-wheels when the slide is moved back, disengaging the carrying-pinions and allowing the adding-wheels to be turned until their further movement is prevented by the stopbar J. In this position these adding-wheels are designed to show 0 at the sight-slot or in reading position. When the slide is moved forward, its stop-bar is disengaged and the carrying-pinions are brought into engagement with the adding-wheels. The clamp-screws f engage the shaft m through oblong apertures in the walls of the slots on and are provided each with a collar f thereon, which by turning the screw binds the frame securely to the shaft.

The first adding-wheel of the cent series is provided with a lateral toothed disk h to engage the pinion 7c and the first adding-wheel of the dollar series is provided with a toothed disk 2' to engage the pinion 70".
